Study of the chargino discovery at FCC-hh and inner tracker proposition — •Cédrine Hügli — DESY, Zeuthen, Germany
The Standard Model has been shown to be an incomplete theory. The most popular theory beyond the SM is Supersymmetry (SUSY). Up to now, no evidence for any of the SUSY particles was found, it was only possible to set exclusion regions and limits on their properties. The post LHC era Future Circular Collider (FCC) with a center of mass energy of 100 TeV could be a new possibility to find SUSY particles. In this work the discovery potential of the pure wino (higgsino) with mass 3 TeV (1 TeV) and average lifetime 0.2 ns (0.023 ns) at FCC-hh is studied in the context of the Minimal Supersymmetric Standard Model with Anomaly Mediated Supersymmetry breaking (tan(β)=5, m0=20 TeV and sign(µ)>0). Using simulations of minimum bias events and single chargino interactions in the reference design of the tracker, the fake rate is estimated. Additionally, the influence of the tracker performance on the discovery potential is studied. The fake rate is then used to predict the final discovery potential of the wino (higgsino) at FCC-hh. The possible mass reach for charginos at FCC-hh is found and the mass prediction possibility is studied.
